Official Rules Speed Sailing Records
The International Yacht Racing Union/World Sailing Speed Record Council
(IYRA/WSSRC), with offices based in England, sets rules for and ratifies
sailing speed records. To be considered for a record, a sailor must provide at
their own expense an IYRU/WSSRC-approved observer, a surveyor's measurement
of the prescribed 500-meters course, calibration of all stopwatches by a
certified authority, and radio-equipped timing equipment at both start and
finish. Data from a record-breaking run is submitted to IYRA/WSSRC for
ratification.
Records may be set in any of five classes according to sail area:
| Class | Sail Area (m^2) | Sail Area (ft^2) |
| Under 10m^2 | Up to 10 | Up to 107 |
| Class A | 10 to 14 | 107 to 149 |
| Class B | 14 to 22 | 149 to 234 |
| Class C | 22 to 28 | 234 to 298 |
| Class D | Over 28 | Over 298 |
